Short-distance constraints in hadronic-light-by-light for the muon g − 2

Abstract

In this talk recent progress in studying the short-distance properties of the hadronic light-by-light contribution to the muon g−2 is described. The intermediate and short-distance part contributes a large part of the error of the theoretical prediction as described in the white paper [1]. We showed that the massless quark-loop is the first term in a systematic expansion at short-distances, a result already used in [1]. Newer results conclude that both nonperturbative and perturbative corrections are under control. The talk describes these developments and how they fit in the total theoretical prediction for the muon g − 2.
